OK, let's get this party started.
Background (even though no one cares)
First time I laid eyes on Gary Byrum's (first) APRO Lander I fell in love with the design, and decided to build my own version of it, despite my trepidation at dealing with those gigantic transitions (prior to this build I had never rolled a single paper shroud). Later when Gary built another one I paid close attention and learned what I could.
When I started to prepare for the Biohazard build, I decided to get my fins laser cut. Well, there was a minimum charge, and the Biohazard parts were going to be way under the minimum, so I (not so) hastily pulled together my APRO design (which I am creatively naming "APRO Lander II"), and got that balsa done at the same time. The fact that I got the wood laser cut for this rocket had a big influence on its construction, because I could never have done what I did with hand cutting (as you'll see).
I have been nervous about starting this build because there are so many ways for me to screw it up. But now that Biohazard is finished, I guess I can't put it off any longer.
I promise there will be at least a few interesting and/or odd things in this build.
Here's the design I ended up with: it's a bit different on the outside, and wildly different on the inside. ORK file is attached at the bottom.
Render:
Side View from OR:
The most immediately obvious difference (other than the fin design, which is mostly cosmetic) is that I run my BT80 all the way to the back of the rocket, and mount the fins to it, rather than the BT55 in the center. I did that because I thought it would ultimately be a bit easier, with smaller fins and less total surface area for the big centering ring (that's a 6" diameter ring) in the back.
